The country isn't going to break apart it just needs to stop letting idiots vote for Biden because "Orange Man Bad" if you know what I mean.
I'd say there is a lot more wrong than that liberals voting for Biden because they don't like Trump. And in ~1.5 years a shytload of people are going to vote Trump out of hatred for Biden.
Kentucky is trying to pass laws to basically exempt themselves from federal gun regulations. We have Texas trying to take political semi-autonym away from their cities. Eastern Oregon wants to secede. In Arizona any election won by a Dem will be disputed for the foreseeable future. The USSC could have found in favor of Dobbs in Dobbs v Jackson and declared Mississippi's Gestational Age Act to be consistent with Roe v Wade (which clearly it is). Instead the conservatives on the bench chose to overturn Roe v Wade entirely; talk about judical over-reach. Justice Thomas has declared gay sex, gay marriage & access to contraception should be "looked at;" more judicial over-reach.
On the other side of the fence, we have folks who no longer want laws enforced, especially if they disproportionately affect certain minorities. They want effeminate males competing in women's sports (my daughter thanks you). Many on the left want to expose children to "alternate gender concepts" as early and often as possible. The want full unfettered and unregulated access to abortion. Much/most of the left wants to socialize healthcare and higher education. They want to register firearms, require licensing, close background check loopholes and enact enforce red flag laws (unless it turns out red flag laws disproportionately affect browns and blacks).
How does voting for somebody other Biden or changing their motives for voting for Biden bridge the divide I just described?
